Stanford researchers used new software to trace ancestry across animal genomes and found multiple coyote DNA segments in chihuahuas.
WASHINGTON — If you have ever wondered why chihuahuas seem to possess the confidence of a much larger, wilder animal, scientists may now have an explanation for you. A new study published in the journal Nature Communications found chihuahuas share parts of their genetic makeup with wild coyotes.
Researchers at Stanford University stumbled on the finding while testing a new pair of software programs, called Gnomix and Gnofix, designed to analyze the genomes of many animals at once and map out their evolutionary history.
The technique, known as local ancestry inference, allows scientists to identify the ...
